WEATHER CONDITIONS IN MUI WO
Automatic Weather Station (AWS)



The automatic weather station (AWS) is located in Mui Wo (Lantau Island, Hong Kong). This AWS should be able to provide weather information for the eastern part of Lantau Island.

This AWS is equipped with Vantage Pro2™ Cabled Integrated Sensor Suite with Cabled Weather Envoy and WeatherLink software from Davis and is capable of measuring temperature, relative humidity, dew point temperature, barometric pressure, rainfall, wind speed and wind direction.
